Home Forums Hunting & Shooting Hunting Rifles 7mm Rem, Magnum 175gr Core-Lokt for deer

I know a lot of hunters use the 140 and 150 grain Remington Core-lokts in 7mm Rem Mag for deer hunting and do quite well with them. I was at the range the other day, and ran across two shooters sighting in there 7 mags useing 175 core-lokts. I ask what they were hunting and thet replied...deer. I personaly like the 140's for deer but hard to find around here so I use the 150's. I always thought the 175's were thicker jacketed and made for killing Buicks. Has anyone used the 175's for deer? Will they expand as well as the 150's or 140's in the core-lokt? The reason I'm asking is they shoot darn well in mine and was thinking of useing them myself.

I wouldn't consider a Core-lokt of any weight a GIANT slayer.

You'll be fine

It's a killer in the underloaded 7mm Mauser. If anything I would be hesitant to use a cup and core from a 7RM.

How come? I have taken countless deer and several large hogs(350lb plus) with them.

Do you get good exspansion at 7 X 57 velocity's on deer?

IF, you are trying to run the bullet "bow to Stern" on every shot,go for it....You a good tracker?

I wouldn't consider countless deer and a 350 pound hog as giants either.

Point being is you seem to be thinking that the 175 Core-lokt is meant for mastodon and I wouldn't consider and one them as such.

Steelhead,
Yes I had been thinking that the heaver the bullet in 7mm the thicker or tougher the construction. Meaning deeper penatration for bigger game. In the past I used the 180 PSP core-lokt (30-06)on small Florida deer for years. Many times the bullet would stop just under the skin on the far side. Especialy on shots 150 - 250 yards. I was givin a handful of 220's and tried them. They just penciled threw and the tracking was on after that.After finding them, even though it was a good lung shot I had to look for the exit hole. Same size as the bullet. No exspansion.

Why would you need that heavy a bullet for deer in the 7 mag?

Bang flop, all you need is the 154g Hornady Sp. Use the same load that you use on the 150g on the 154g.

Buy youself a .257 Bob,6.5x55...25-06,115 grains will kill them deer...

duckster,

I don't believe you do by any means. I was just wondering because they shoot VERY tight groups out of several rifles. I was wondering with the .250 groups these guys were shooting with them and my gun as well.....how they would do on deer? Like I said before, I prefer the 140's but can't find them so I use the 150's But if they will work just as good,they shoot good, easy to find and there cheap to buy.

I have to agree that is a bullet weight that is a little heavy for deer. Our Eastern deer don't take much killing.

But....

If it is that much more accurate than your 150gr loads, have at it. You definitely won't have any issues busting through shoulders.

Dead is dead.

yep 154gr hornady does great in 7mm mag and 284 win

Got one, Ruger MKII VT in 25-06 Remington, Yep I shoot 115 Noslers in it. Best shooting rifle I own. But when I go hunting I like my little 7mag. It has NEVER failed to drop any game I have shot at. I just trust it. Personal thing I guess

Work up a good load with a 160 and use it on everything. As always, NP's would be a good first choice.

Yep, know what you mean. I used to load the 154 Hornady RN in my old 7 mag. That was one great round. But new job, don't have time to reload at the moment. With my new rifle I wanted to just be able to go to wally world or where ever and pick up some Remingtons and hunt with them. With the 150's I get 3/4 groups which is plenty good enough for me to hunt with. The 175's I get 1/4" groups. But have never used them to hunt with.

Never used the 175 Remington but have killed several whitetail deer in West Virginia with 175 Sierra SBT. No problems with expansion and have killed deer out to 1000 plus yards with them. This was of course with a 7mmMag Remington. Did everything from head shots at paces and long shots in lots of yards.

my old man uses them in his 7mm rem mag for moose so you should have no problems on a deer.

Knwh51,

Thank you, that was a big help. I have friends at Remington,They tell me in the 30-06, the 180 is the same jacket thickness as the 150. The 180 is just longer. So it works well even on small deer. I don't know if thats true with all calibers they load in that line

I was curious if the 175 in the 7 mag (factory load) was the same as the 150... just longer. Same Jacket thickness and hardness ? That's the magic question
